TiN-PLATEfc'A'rcnING MACHINE.

A To all whom 'it may concern:

imme 'Be it knownthat I, GEORGE J. SzABo, a citizen of the United States, residing at Portvue, in the county of vAllegheny and Sta-te of Pennsylvania, have invented certain new and useful Improvements in Tin: Plate-Catching Machines, and do declare that the following is a full, clear, and exact description 'of the inventinn, which will enable .l0

othersl skilled in 'the art to which it appertains to make and use thesame.

My invention relates to a machine to catch tin plates, and the inventioiiconsists in a machine constructed and adapted tooperate,

4 substantially as shown and described and particularly pointedout in the claims.

In theaccompanying drawings, F igurel isa side elevation of the machine, and Fig.

2 is 'an end elevationthereof. Fig. 3 like' wise is an end elevation but opposite to that shown in Fig. 2. Fig. 4 is a cross section of the machine on -a line corresponding substantially to :ii-"r, Fig. 1. Fig. 5 is an enlarged sectional view of one of the yielding catching wheels for the tin plate. Fig. 6 is a plan view of the main part of the machine I showing the chute and conveyer and t-he meansfor shifting the plate to lie longitudinally on the conveyer. Fig. -7 is a cross section on line 7--7, Fig. 6.

In these several views like reference characters indicate like parts, and the machine as a whole is intended for use in an .establishment where tin plates are manufactured and the `pla-tes are taken ca re of durin the time the tin is being applied-and iately thereafter, the term plate catcher or catching being usually employed to describe what is accomplished by this machine.

To these ends the parts of the machine ,comprise a tank T in or at the vbott-om thereof and a frame F erected and adapted to be tiltingly fixed thereon, and which carries most or all of the operating mechanism. This mechanism has to do more especially with the sheet plate P as it emerges from the tinning tank or bath T and passes 'up through the oil space or receptacle t in the upper portion thereof and through the two sets of rolls or rollers'R between which the plate is carried `upward in the usual way.

As to .the said tank T. and oil reservoir or space in the top thereof and the rolls R it therefor as such and alone in this case, and 'the usual construction of said parts vmay be adopted.v Novelty begins, however, in frame F, which is shown as pivoted'on short fixed ,posts2 and adapted to be bodily tilted on said pivots so as to afford free access to the oil.

chamber and tank from above when, for any reason, such access shall become `necessary. Otherwisesaid frame is seated on said tank. i y

Now, in handling tin plates as they emerge from the molten bath in tank T and pass thence upward between rolls R it is of the ,greatestimportance that 'said 'plates be not marred nor otherwise injured upon their.

surface in such snbsequent handling,x and while various-devices have lbeen Y employed heretofore to avoid this objection and to promote .the delivery of the plates with .un-

impaired surfaces, I am not aware that any of them have been really satisfactory in operation and effect, and especially am not aware that any such devices for this pur-l pose as ,constitutel my present inventionhave ever before been known or used. Now, tak-` ing up this portion of my improvement in detail, it will be seen that the plates I pass from rolls R to wheels B and B', a series of which are mounted at. intervals aparton 'each shaft S and ada ted to engage .and

carry or raise plates Il therewith and deposit them on such higher level and in such 4manner and relation that said plates can betaken care of after passing over discharge rolls D, or their equivalent, in any suitable way,'but preferably as hereinafter described. As to said wheels B, it will be seen` that they have bands or rims b of greater or less width and radial spokes 4 and 5, or rather. that short stubs of spoke sections 4 are' on said bands -and longer spokes ,or sections 5 on the hubs of the by direct contact spcincatin of Lettersratent.

wheel, 'and'spiral springs 6 encircle'each spokeA as a whole and exact outward pressure against said -band lwhile -at the samev time they hold the band in right workingl The said bandi ioo ' Plates'or disks b2 handling of the stock is assured.. As a fur-- ther prevention of injury to the plates, band of wheel B andthe band of wheel B are provided with encircling rings' b of tin. are also fixed upon the hub of wheels B to hold the band against lateral ations for. long movement but these plates are otherwise freetto'spcrmit play of the band in respect lto vThe shafts are supported on cross bars C at their ends,

to accommodate'the elevation of said Wheels to the length or elevation of the plate in re-V spect to rolls R. Such elevation and adjustment is further accommodated by slots 12 in the upright posts of frame F, while bolts 1.3 further help to fix adjustments. Guides G coperate with wheels B in directing the plates over rf-s D t the to conveyer orv belt C. 0th may be safe delivery of the plates desirable.

The 'adjustments .and accommodations hereinbefore provided are found necessary in order to maintain perfect'working operperiods of time. Thus, it occurs in theoperation of the machine that the rolls Rhave to be trued up occasionally by reason of unevenness 'developing on their surfaces, and in doing this said rolls become reduced in cross section. Provision is therefore usually made for lateral adjust# ment intheir bearings to take u such wear and reduction, but a reduced iameter effects their speed of'rotation.' Hence a corresponding speed accommodation must be provided for in the sheet-engaging wheels B, so that they will be timed to turn in exact unison with rollers R.4 This requires somewhat peculiar -transmitting mechanism and which consists in this instance in a seer stays or guides as may be' deemed ries of three gears 17, 18 and 19, or their equivalent, proceeding from shaft J and having intermediate gear 18 supported in more or less extensible angular relation to the other two by links 20 and 2l,-thereby permittingthe upper gear and maintaining operating relation, therewith of the connecting gear -18 in any and all cases. The links 20 connect with shaft .I at one end,` and links 21 with shaft 23' whichcarries gear 19, and at their'other ends said links connect with the spindle of wheel 18. Now, speed variation or variablevariableness inthe sizes and speed of rotawhichare vertically adjust# able on or in main frame F, and screw rods -81 and nuts 9 serve to make such adjustment chute E,Aand thencev used here and there to promote theV ers R by 19 of the series' of three to b e more or less raised or lowered tion of rollers R, whence gear connection is made With wheels B. To, these ends l pro-- vide two reversely tapered friction rolls 3G and 31, supported at their ends in a frame 32 ada ted to be vertically adjusted in frame F ,y means of screws 33 and nuts 34, suit able engagement being provided for said frame 32 with or in slots 35 in said frame F.

A drive b and 36 operatively unites said rolls 30 and tion according to the speed wanted by means of hand controlled screw 37 and a band engaging and confining device 38 mounted on said screw. Power is derived through roll 30 to roll 31 by band 36, and transmitted by gear 38 on shaft 39 carrying said roll 31. This shaft, 39, is lengthwise adjustable vto disengage gear 38 when occasion requires Vand 'occurs when frame F is tilted, as here inbefore described, it being understood that frame F is'rigid with the base. The ear 38 meshes with large gear 40, mounted on shaft S andwhich carries a gear 4l: at its opposite end. This gear meshes with a gear p of exactly the same slze on the'opposite shaft S, so that the wheels B on said shafts rotate exactly, alike. The roller-D is shown as an idler in ,this instance, but it may be geared u with the power mechanism if preferred. Bower is communicated to.feed rollor through gear 45 on shaft J. Itis to be understood that I do not confine myself to the yexact proportions of wheels or rolls B and B o n shafts S and S', as obviously these rolls may have a wider engaging surface if preferred and even take on the form of rollers more or less like feed rollers R. Other details also may be varied and not depart from the spirit of the invention.

Now, when plate P is carried upward and delivered toinclined chute E, it will slide by gravity down the same until it rests on conveyer C which will carry it away.' Chute E may have an open bottom of slats or. it may be. corrugated or ribbed as shown to lessen the number and area of contact surfaces with the plate, and said chute is preferably constructed as light in weight as the work will permit and is a detachable and removable part of frame l" upon which it is hooked by any one of the series of fingerse when engaged with cross bar f. Arms f on the frame have set screws f2 which bear against the bottom of chute E to adjust the angle of the same more or'less in respect to conveyer C. This conveyer is usually of suitable width to carry plates P of varying widths but as said plates differ very greatly in length, I have provided .chute E with turning devices-K, one ateach side, wherewith the plate will engage at its end edge nearvone longitudinal side edge thereof-on the down travel of the plate. These devices each comprise a curved strip 31 and is adjusted for working posi K secured to 'a rod K which is adjustably held by a set Screw K2 in an adjustable bracket K8 on chute E. Thus, when a'plate- P is fed into the chute, be it at one side or the movement. Frame C2 of conveyer C is provided-with-lengthwise guards C3 at either side t'o prevent plate C from riding off the conveyor when first transferred thereto and thereafter.
